The new trailer released at Comic-Con International: San Diego offers our first look at live-action footage of the villain Steppenwolf in action.

The trailer above shows Steppenwolf arriving on Themyscira and doing battle with members of the Justice League, including slamming his ax against Wonder Woman’s bracers.

Steppenwolf was first hinted at in a scene that was deleted from the theatrical cut of Batman v Superman: Dawn of Justice in which Lex Luthor examines the databanks of a Kryptonian ship. A three-dimensional image of Steppenwolf is then shown examining Mother Boxes. The scene was released online shortly after Batman v Superman: Dawn of Justice was released into theaters and was restored in the Ultimate Edition of the film.

Steppenwolf is the uncle of Darkseid, the tyrannical ruler of Apokolips, and one of Darkseid’s elite generals. It is theorized that Steppenwolf, played by Game of Thrones alum Ciarán Hinds, will lead the invasion of Earth in Justice League.

Until now, the only idea fans had of how Steppenwolf would look was via the Batman v Superman: Dawn of Justice scene and toys that have released early to retailers. Seeing the general of Apokolips in action against the Justice League is certainly something else.
